An experiment to search for double beta processes in Cd by using cadmium tungstate crystal scintillator enriched in Cd (106CdWO4) in coincidence with the four crystals HPGe detector GeMulti is in progress at the STELLA facility of the Gran Sasso underground laboratory of INFN (Italy). The 106CdWO4 scintillator is viewed by a low-background photomultiplier tube through a lead tungstate crystal l...
In this paper we discuss the Smart Positron Emission Tomography (PET) imaging system being developed by the University of Liverpool in conjunction with CCLRC Daresbury Laboratory. We describe the motivation for the development of a semiconductorbased PET system and the advantages it will offer over current tomographs. Details of the detectors and associated electronics are discussed and results...
The portable germanium detector based HHRIDs are generally intended to be operated in low to medium radiation fields with as much sensitivity as possible. However, in some circumstances the interfering radioactive background may be significant with respect to the source of interest. For example: a shipping container full of NORM may be used in an attempt to mask the presence of a concealed SNM ...
below and are based on some basic concepts about how the detection process works, how gamma rays penetrate materials, and the principles of gamma-ray spectroscopy. Unresolved choice issues can be reduced to a level where they have little or no impact on the resultant performance of the spectrometry system. This document explains how you can easily make a wise, well-informed choice. We assume yo...
در این مقاله بیناب نوترونهای سریع ارتفاعهای 3 و 5 کیلومتری سطح زمین با استفاده از پاسخ آشکارسازهای قطرهی فوق گرم بهرهگیری شبکهی هوشمند عصبی فازی (انفیس) بازیابی شد. انفیس، یک سیستم استنتاج نوع تاکاگی- سوگنو است که قالب تطبیقی پیادهسازی شده است. ابزار مشابه تفکر انسان مواجه مسایل غیرقطعی همراه خطا عمل میکند. ماتریس پنج آشکارساز فوقگرم فشارهای خارجی مختلف توسط برنامهی کاربردی نو...
